Suddenly a volley of shots sounded some distance ahead of him, followed by a series of yells as if the mountains were alive with savage redskins.

It was Bud Stevens. The wild herd had come upon him just as they were about to turn northward and dive into the fastnesses of the mountains. Observing him they turned slightly to the west and continued on their mad course.

"Good boy!" Bud shrieked. "Draw up on 'em! Draw up on 'em!"

Tad did. It was a race, but a most perilous one. To the boy it seemed as if the feet of his pony were off the ground most of the time, his run having merged into a series of long, curving leaps as it reached from rock to rock.

Down a steep slope suddenly plunged the herd. Tad saw the flying pony of Bud Stevens directly abreast of them. The lad, apparently feeling no fear, brought his quirt down sharply on the flanks of his mount. The pony hesitated, rose and took a flying leap fully ten feet down the mountain side before its feet braced sharply and thus saved pony and rider from plunging on over.

Now Tad was yelling at the top of his voice, as that seemed the proper thing to do under the circumstances.

The wild band was heading for the open, just as Bud Stevens had planned. But the fleeing horses were seeking to get out on the open plain where they might soon outdistance their pursuers.

Tad and his pony went down that rugged mountain side as if the pony were a mountain goat. The boy never had experienced such a thrilling ride, and the jolts he got made his head dizzy.

"M-m-my, this is going some!" he gasped.

Tad was shouting for pure joy now. When his mount landed on all fours among the foothills he was not more than two minutes behind Bud Stevens himself.
